Step-by-step explanation:
The volume of a cylinder is 
- r is the radius (half of the diameter which is 34m) --> 17m
- height: 27m
: 3.14
Thus the volume =

Answer: x=68/11 and y=-72/11
Steps:
2(x+4y=-20)
2x+8y=-40
2x - 3y = 32
- 2x + 8y = -40
-11y=72
y=-72/11
x + 4(-72/11) = -20
x - 288/11 = -20
x=68/11
(i) The scale factor is 6 because of the ratio between the 2 given corresponding sides.
I don't know the second part, but I hope this helps regardless.
